System Description

EKS00FUL

Daytime light system turns on daytime light lamps while driving. Daytime light lamps are not turned on if
engine is activated with parking brake on. Take off parking brake to turn on daytime light lamps. The lamps
turn off when lighting switch is in the 2ND position or AUTO position (Headlamp is "ON") and when lighting
switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line.

Power is supplied at all times

●

to ignition relay, located in the IPDM E/R, and

●

through 10A fuse [No. 19, located in the fuse block (J/B)]

●

to combination meter terminal 3, and

●

through 20A fuse (No. 53, located in the IPDM E/R)

●

to CPU (central processing unit) of IPDM E/R (intelligent power distribution module engine room), and

●

to headlamp high relay, located in the IPDM E/R, and

●

to headlamp low relay, located in the IPDM E/R, and

●

through 50A fusible link (letter g , located in the fuse and fusible link box)

●

to BCM terminal 70, and

●

through 10A fuse (No. 45, located in the IPDM E/R)

●

to daytime light relay 1 terminals 2 and 5.

When the ignition switch is in ON or START position, power is supplied

●

to ignition relay, located in the IPDM E/R, and

●

through 10A fuse [No. 14, located in the fuse block (J/B)]

●

to combination meter terminal 16, and

●

through 10A fuse [No. 1, located in the fuse block (J/B)]

●

to BCM terminal 38.

Ground is supplied

●

to BCM terminal 67 and

●

to combination meter terminals 13 and 23

●

through grounds M57, M61 and M79.

Low Beam Operation

With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R con-
trols the headlamp low relay coil. When energized, this relay directs power

●

through 15A fuse (No. 41, located in the IPDM E/R)

●

through IPDM E/R terminal 54

●

to front headlamp RH terminal 3, and

●

through 15A fuse (No. 40, located in the IPDM E/R)

●

through IPDM E/R terminal 52

●

to daytime light relay 2 terminals 2 and 5, and

●

through daytime light relay 2 terminal 3

●

to front headlamp LH terminal 3.

Ground is supplied

●

to front headlamp RH terminal 2

●

to daytime light relay 1 terminal 4

●

to daytime light relay 2 terminal 1

●

through grounds E9, E15 and E24.

When the CPU of the IPDM E/R energizes the headlamp low relay, it de-energizes daytime relay 1. When de-
energized, this relay supplies ground

●

to front headlamp LH terminal 2

●

through daytime light relay 1 terminal 3.

With power and ground supplied, low beam headlamps illuminate.

High Beam Operation/Flash-to-Pass Operation

With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CAN com-

munication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator.
The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power

through IPDM E/R terminal 55

●

to front headlamp LH terminal 1.

Ground is supplied

●

to front headlamp RH terminal 2,

●

to daytime light relay 1 terminal 4, and

●

to daytime light relay 2 terminal 1

●

through grounds E9, E15 and E24.

When the CPU of the IPDM E/R energizes the headlamp high relay, it de-energizes daytime relay 1. When de-
energized, this relay supplies ground

●

to front headlamp LH terminal 2

●

through daytime light relay 1 terminal 3.

With power and ground supplied, the high beam headlamps illuminate.

DAYTIME LIGHT OPERATION

With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the IPDM
E/R receives input requesting the daytime lights illuminate. This input is communicated across the CAN com-
munication lines. The CPU of the IPDM E/R controls daytime light relay 1 coil. When energized, this relay
directs power

With power and ground supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
